Me gustaria que me explicaran como hacer una id para ese bot ,como hago para conectarlo mediante el sistema UPD de winsock ,ahora les dejo el codigo de luigi ,si me podrian explicar como hace para tener un nick y conectarce ,y que fi¡gure en el score como un player se los agradeceria ,desde ya muchas gracias
